There are plenty of commercially available solutions to dealing with pesky weeds in your lawn or garden. However, while they might be an excellent option for dealing with weeds, most of these products include toxic chemicals like Glyphosate. These chemicals can be dangerous for people, animals, and the environment.

For a lot of us, our pet is a member of the family, and keeping them safe is a priority. That’s why I encourage you to ditch the chemicals and find a new solution to dealing with weeds. Using an organic weed killer and doesn’t pose negative health risks to you, your family, or your pets.

Why Use an Organic Weed Killer?

Using organic weed control products is an environmentally responsible and health-conscious choice that offers many benefits. These are just some of the benefits these natural products have over their artificial counterparts.

Nontoxic

Artificial weed treatment products like RoundUp contain dangerous chemicals like Glyphosate. Glyphosate is a carcinogen and can pose health risks to children or pets when sprayed in a residential area.

This is in stark contrast to organic products, which are free of any harmful chemicals. This makes them safe to use anywhere and a responsible choice for residential use.

Safer for the environment

Chemical herbicides are dangerous for birds, can contaminate runoff water, and might be one of the causes behind bees dying. Organic weed killing products are biodegradable and pose much less risk to the environment.

Sustainability

Organic weed killers are made using sustainable natural ingredients. The active ingredients in organic weed killers are all derived from plants. It’s all-natural, and it’s sustainable because you can keep growing these crops over and over.

Epoma Organic Weed Preventer

Espoma Organic Weed Preventer is an organic weed and feed product. It’s made from corn gluten meal, an all-natural byproduct from the manufacturing of cornstarch.

Weed and feed is a generic name for products that both strengthen grass and control weeds in one application. Epoma’s corn gluten spread prevents weeds while providing nitrogen to the soil as it naturally decays. This feeds your lawn and leads to thicker and greener grass.

This product doesn’t kill weeds that are already grown. Instead, it prevents new ones from growing in the first place. It does this without hurting any already grown plants by preventing seeds from successfully sprouting roots. Spreading it in March and April before weeds can start taking root will keep your yard weed-free over the summer.

Pros:

  • Prevents troublesome weeds from taking root
  • Children and pets can safely play on the lawn after application
  • Also safe for use in vegetable gardens

Cons:

  • Will not prevent the regrowth of weeds with established roots, including perennial weeds.
  • You will not be able to plant anything in the applied area for 6 months after spreading this product without scraping away the topsoil.

Preen Natural Vegetable Garden Weed Preventer

This product by Preen is another organic weed and feed product that prevents weeds from growing in your lawn or garden.

Preen Natural Vegetable Garden Weed Preventer is also made with 100% corn gluten meal. It naturally provides nitrogen to soil while preventing new weeds from growing in the soil. This means a healthy and weed-free lawn or garden.

It’s also entirely safe for pets or kids to be around and play on the lawn even after you have just applied it.

Something that I really like about Preen’s version of this product is that the container it comes in has a filter cap that makes spreading it fast and easy. This is only the case with the smaller options though. Larger sizes of this product are sold in a bag instead.

Pros:

  • Flip-top applicator cap makes it easy to apply
  • An excellent choice to prevent weeds in your vegetable or herb garden
  • Prevents crabgrass, dandelions, clover, and other common weeds

Cons:

  • More expensive per pound than Epoma Organic Weed Preventer
  • It can prevent friendly plants from growing for up to 2 months while active in the soil unless you scrape away the topsoil when planting or transplanting plants.

How do organic weed killers work?

Organic pet safe weed killers keep dogs and cats safe from potentially harmful chemicals.

Organic weed killers don’t contain harmful chemicals like Glyphosate, instead they use natural alternatives to accomplish the same jobs. There are a few different common ingredients that natural weed killers use to accomplish these tasks. These are some of the most common ones:

Vinegar

Vinegar is an organic product that can be made from fruits and grains by fermenting them. The process is a lot like the one used to make alcohol only with a few extra steps involved. This process creates a substance called acetic acid, which is what provides vinegar with its plant-killing power.

When its sprayed onto the leaves of a plant, vinegar kills it by draining out the plant’s moisture. At the higher concentrations of acetic acid in horticultural vinegar, this effect is amplified.

Clove Oil

Clove oil is an essential oil that’s derived from clove trees by distilling dried flower buds that are collected from the tree. It contains a natural compound called eugenol that gives it similar plant-killing powers to vinegar. Like vinegar, when it is sprayed onto the leaves of a plant, clove oil will pull out the moisture of that plant to destroy it.

Salt

Salt also dries out plants either through contact with their leaves or roots. There is some danger with using salt in areas where you still want plants to be able to grow because it can stay in the soil and raise its salinity. Therefore, products containing it usually only have a small percentage or warn that it should not be used in gardens or on lawns.

This does makes these mixtures very useful for places like cracks in your driveway where you do not want anything to grow back.

Corn Gluten Meal

A byproduct of creating cornstarch, corn gluten meal has natural pre-emergent weed control properties. This means that it can prevent weeds from taking root and growing. It’s also high in nitrogen and enriches the soil as it breaks down, making it a popular choice as an all-natural weed and feed alternative.

While active in the soil it will also prevent any seeds you try to plant from growing, so it’s a good idea to apply it only after your plants have sprouted. Alternatively, you could also scrape away the topsoil in the location you are planting the seed to remove the corn gluten meal from that spot while planting.

What are other methods of natural weed control that I can try?

There are some proven methods of natural weed control that you can perform at your home without needing to buy a commercial weed killer.

Mulch

Using mulch to cover empty space in your yard or garden is a great way to prevent unsightly weeds.

Not only does an excellent organic mulch look great, but it prevents plant growth by depriving them of the sunlight they need to survive. This is just one of the many benefits that mulch can bring to a garden.

Boiling Water

Probably the most straightforward and cheapest method of dealing with a small patch of weeds is throwing boiling water onto it. Boiling water will kill most plant life that you throw it onto.

This makes pouring boiling hot water onto weeds can be an effective way to deal with a small patch of weeds. It won’t prevent them from growing back though.

Conclusion

Using organic weed killers like Green Gobbler Weed Killer and other natural methods of weed control is a responsible way to keep yourself, your family and your pets safe. It also helps protect the environment with biodegradable ingredients that are sustainability grown. Join the growing revolution towards green gardening today.
